SMOKING-PIPE.

SPECIFICATION forming part of Letters Patent No. 779,694, dated January10, 1905. Application filed February 13, 1904. Serial No. 193,420.

To (LZZ whom, it ntay concern-.-

Be it known that I, GEORGE BENJAMIN NOR- TON Dow, a citizen of theUnited States, residing at Manchester, county of Hillsboro, State of NewHampshire, have invented certain new and useful Improvements inSmoking-Pipes, of which the following is a specification.

This invention relates to pipes, and particularly to pipes for thesmoking of tobacco. Many who consume tobacco in this manner when for anyreason they are compelled to stop before the tobacco in the bowl iscompletely consumed desire to retain the unburned charge and to put awaythe pipe in this condition without danger'of fire or of spilling thetobacco from the bowl.

To this end the present invention contemplates a pipe which shall havemeans for stopping the mouth of the tobacco-opening of the bowl, saidmeans consisting of a stopper associated with the stem and adapted tofit both the bowl-opening and stem-opening.

In the drawings, in which like letters of reference indicatecorresponding parts throughout, Figure l is a view of the pipe; Fig. 2,a section of the same; Fig. 3, a view of the pipe with the bowl closed.Figs. 4 and 6 illustrate modifications of the button structure, and Fig.5 a detail of a further modification.

B is a bowl having recesses B B for tobacco and the pipe-stem,respectively.

S is a stem having the smoke-passage s therethrough.

P is a plug adapted to fit the mouth of either of the openings B B andis pierced by a passage 21 for the smoke. This plug P may be formed onthe stem S as a part thereof, as shown in Fig. 5, or made as a separatememher, as shown in the figures of the drawings, particular attentionbeing called to Figs. 4 and 6, which illustrate various modifications ofthe plug member, which may be of the conical form P or in the form of ashoulder-button, as P The stem S may also be of any form, straight orcurved, and may enter the plug at other than a right angle to the bowl,as shown in the drawings.

The bowl proper is preferably bored with an extension B of smallerdiameter than the tobacco-cavity, leavingon the wall of the pipe betweensaid last-named cavity and the extension an annular shoulder upon whichis located a perforated disk D, which may be of any suitable material,as tin. A slit bushing E, of any suitable material, which may also be oftin, which is found satisfactory in practice, is inserted within thebowl and forced down upon the disk D to retain the same in place andprotect the body of the pipe. If it is desired, the disk and bushing maybe made together in one piece or in the form of a cup, in which form theparts are more readily removed for the purpose of cleaning the pipe orreplacing members which are defective or which have been injured.

The bowl B may be of any suitable internal structure, although the diskand bushing above described are found satisfactory in manufacture; butthis structure and arrangement may obviously be modified or changed, andvarious other forms of plugs may be used without departing from thespirit of my invention.

What I therefore claim, and desire to secure by Letters Patent, is

1. In a pipe, the combination of a bowl having a tobacco-cavity and astem-cavity, and a stem having a plug adapted to fit either of saidcavities.

2. In a pipe, the combination of a bowl member having tobacco and stemopenings, of a perforated plug member adapted to fit either of saidopenings, and a stem member adapted to fit'the perforation in the plugmember.

3. In a pipe, the combination of a bowl member having tobacco and stemopenings, of a perforated tapered plug member adapted to fit either ofsaid openings, and a stem mem ber adapted fit the perforation in theplug member.

4. Inapipe, the combination-ofa bowl member having a tobacco-opening andan extension thereof of smaller diameter, an annular shoulder betweensaid openings, a perforated disk located on said shoulder, astem-opening entering said extension-bore of the tobaccoopening, aperforated tapered plug member adapted to fit either the bowl-opening orthe stem-opening, and a stem to fit said perforated plug. 4

5. In a pipe, the combination of a bowl member having a tobacco-openingand an extension thereof of smaller diameter, an annular shoulderbetween said openings, a perforated I disk located on said shoulder, astem-opening entering said extension-bore of the tobaccoopening, and astem having a plug member adapted to fit either the bowl-opening or thestem-opening.

6. Ina pipe, the combination of abowl member having a tobacco-openingand an extension thereof of smaller diameter, an annular shoulderbetween said openings, aperforated disk located on said shoulder, abushing fitting said bowl above said disk, a stem-opening entering saidextension-bore of the tobaccoopening, and a stem having a plug memberadapted to fit either the bowl-opening or the stem-opening.

In testimony whereof I affix my signature in presence of two witnesses.
